Compact 40 mm 12 V case fan for tight enclosures

The SXDOOL mgt4012mb-r20 measures 40 by 40 by 20 mm and runs on 12 V at 0.11 A. Its double-ball bearing supports a 6300 rpm operating speed. A three-wire lead with a 2.54 mm plug connects directly to standard headers. Designed for H3C telecommunications switches and similar space-constrained chassis.

Sustained airflow with double-ball durability

Double-ball bearings resist wear better than sleeve types during continuous 6300 rpm operation. The low 0.11 A draw keeps power demand modest while the fan maintains steady airflow over long duty cycles. Three-wire feedback allows the host system to monitor speed and adjust as needed. The 2.54 mm connector ensures a secure, vibration-resistant link in rack or wall-mount installations.
